The present invention relates to machines and in general-tonall apparatus serving for the baking of fiat biscuits or"waflies of the type in which the material servingk for the manufacture of the waffles, such as batter or paste, is delivered to molds or irons consisting oi two metal plates movable in relation to each other and carried, for instance, by hinged members, which plates, after the introduction of a layer or batter spread over them, are closed by being placed one against the other and are then either hea-ted on the spot or passed into a heated baking chamber in any manner. f

The object of the present invention is a walile-iron made so as toy obtain comple-te sheets ot waffles without any scraping operation.

ln the accompanying drawings which show the invention by way of example:

Figure l is a vertical sectional view of a type of wallie-iron made in accordance with the invention, and Fig. lA is a plan view of the same.

Figure 2 is 'a side view of one of the strips arranged around the edges ot' the plates, and Fig.2A is a. cross section thereof.

Figure 8 is a partial section of the waileyiron during the closing operation andFigure 4 a similar view of the wa-tlie-iron when closed.

The improved wallie-iron is formed in the known manner by the union of two metal plates c movable relatively toeach other, for instance by rotation about the hinge d.

When the waliie-iron is closed the two plates are held parallel at a slight distance from each other according to the thickness of the sheet to be obtained.

The waffle-iron being opened, a certain quantity of batter is deposited between the plates, and spreads itself between the said plates when the latter are closed.- In order to secure the complete filling of the waiile-iron it is necessary that a greater quantity of batter be provided than would be strictly necessary for obtaining the sheet. The excess batter is forced outwards and forms a portion ot waste which in the ordinary procedure must be removed after baking, by scraping the edges of the waffle-iron with a knife bet'ore removing the sheet. This scraping 0peration is however completely dispensed with by theuse of the present invention.

The waffle-iron is so formed that the space e between the plates is completely or almost completely shut after closing the plates, this: result being obtained, for example, by means ot' metal edging strips a fitted and .secured to either of the plates c.

The strips a, or members substituted therefor, are provided with recesses Z) of variable number and ot' suitable shape, the general direction of which recesses is such that they lie in a plane normal to the Plane of the plates and opening outwards at one end while stopping at the other end at some distance from the space between the plates (Figure 4E). v

In the course ot closing the plates (Figure 3) the vapours produced by the baking escape through t-he recesses I) in the direction of the arrow and the section of said recesses is so chosen that the speed of outiiow of the vapours is considerable. Owing to the suddenchange of direction in the flow of the vapours caused by the shape ot the recesses, the tract-ion exerted on the batter (of which the inertia is considerable) by the vapours is extremely reduced and the waste appears in the form of small pellets f of batter at the exit of the recesses.

When the closing is completed (Figure it) the waste pellets are out ott and separated from the sheet of wattles the edges of which are left perfect-ly clean. f

On opening the plates the waste f falls oil of itself leaving the sheet intact and complete.

The accompanying figures illust-rate a special production by means of applied edging-strips, but the invention extends to all arrangements in which the space between the plates is practically closed when the waffle-iron is closed and the vapour escapes during closing through narrow conduits showing a sudden change of direction.

I claim as my invention:

l. A waliie iron, comprising a pair of hingedly-connected, coacting plates having narrow recesses at their margins for the escape ot vapours and excess batter from the iron when the plates are practically, but not completely, closed together and to shear oit' the excess batter when said plates are completely closed; said recesses being so shaped as to produce an abrupt change in the direction o movement of the escaping vapours and thereby canse the latter to reduce the traction exerted on the batter.

2. A wallie iron, comprising a pair of hingeelly-connected, coacting plates, and metal edging strips attached to the plates and extending along their marginal faces in position to close the space between the plates when the latter are practically closed together; said strips having formed in their inner Lt'aces narrow recesses for the escape of vapours and excess batter which are adapted to communicate with such space and are so shaped as to produce an abrupt change in the direction of movement of the escaping vapours and thereby cause the latter to reduce the traction exerted on the batter.

3. A wai'lle iron, according to claim 2, in which the inner ends of the recesses are moved past the space between the hinged plates when the latter are completely closed together, whereby the excess batter in the recesses is sheared from the sheet of batter between said plates. Y

In testimony whereof I affix my signature.
